RIPEMD-160
http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html
This is my implementation of RIPEMD-160. The pentium assembler is a little
off the pace since I only get 1050 cycles, while the best is 1013.
I have a few ideas for how to get another 20 or so cycles, but at
this point I will not bother right now. I believe the trick will be
to remove my 'copy X array onto stack' until inside the RIP1() finctions the
first time round. To do this I need another register and will only have one
temporary one. A bit tricky.... I can also cleanup the saving of the 5 words
after the first half of the calculation. I should read the origional
value, add then write. Currently I just save the new and read the origioal.
I then read both at the end. Bad.
